WILLIAM MCCORMICK AND HARRY BARNES, OF CLEVELAND, OHIO.

FLUSHING-TANK.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed November 17,1906. Serial No. 343,892.

To all whom it may concern:

Be it known that we, WILLIAM MCCORMICK and HARRY BARNES, citizens of theUnited States, residing at Cleveland, in the county of Ouyahoga andState of Ohio, have invented new and useful Improvements inFlushing-Tanks, of which the following is a specification.

This invention relates particularly to flushing tanks for water closets.

An ordinary wooden tank, lined directly with metal, is subject towarping or splitting, caused by condensation of water on the outside orby leak from the inside. Such tanks are also diflicult to remove, thewoodwork usually being rigidly fixed to the wall, and hence also subjectto defacement or injury when the walls of the room are being papered,painted or otherwise repaired.

The object of the present invention is to avoid the defects mentioned.This is done by providing an outer detachable casing for the tank, whichcan be quickly removed or replaced without disturbing the tank proper.The outer casing is spaced from the tank, so that an air circulation isprovided therebetween, which avoids condensation incident to the coldwater, and also avoids any injury from possible leakage.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a perspective view of the complete tank. Fig. 2 is a topview with the cover removed. Fig. 3 is a perspective view of the casingdetached. Fig. 4 is a perspective view of the tank proper.

The invention is particularly adapted for low down closet tanks, but isapplicable to other tanks used for water closet or other purposes.

Referring specifically to the drawings, the tank prop er is indicated at6, consisting of a box which may be made of cheap or rough stuff, with ametallic lining as usual. This box is supported by brackets at the ends,by which it is attached to the wall. Each bracket consists of a plate 7secured to the end of the box, having outwardly-extending flanges 8 atits top and bottom edges and a connecting flange 9 at its rear edge. Theflange 9 is secured to the wall or other support by nails or screws,which may be inserted through holes 10. The flange 9 is ordinarily flushwith the backboard of the box, so that the box sets close against thewall. The front edge of the plate, however, may be extended a shortdistance beyond the front of the box. This box or tank has the usualinlet and outlet connections for the purpose to which it is applied. Theouter removable casing is preferably made of fine or polished stock,consisting of a front board 11 and end pieces 12 joined thereto. Thiscasing is of a size suflicient to extend around or inclose the tank andto provide an air space therebetween. The casing is supported on thetank by means of brackets 13 secured to the front and end boards andhaving upper and lower hooked lugs 14 which take into holes 15 in theflanges 8 of the end plates. A cover 16 is provided to rest upon the topof the casing.

To provide for an air circulation between the tank and the casing, andto admit air into the tank when the same is emptied, the front 11 andends 12 have notches 17 in the top edge, and the end pieces of the tank6 have corresponding notches 18, so that a flow of air is allowedthrough the open bottom of the casing and through the space between thecasing and the tank, and also when the tank is emptied a suflicientpassage of the necessary air is permitted, without objectionable noise.The casing may be instantly removed by lifting the same to disengage thehooks 14 from the holes.

We claim:

1.. The combination of a tank having flanges projecting from the sidewalls thereof and provided with holes, and an outer casing extendingaround and spaced from the tank and having brackets with inwardlyprojecting hooked lugs engaging in the holes.

2. The combination of a tank, plates secured to the ends thereof havingflanges at the top, bottom and rear edges, and an outer casing extendingaround and spaced from the tank and having brackets with inwardlyprojecting lugs resting on the top and bottom flanges.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
